Quando você precisa enviar dados de um cliente (como de um navegador) para sua API, você os envia como um **corpo da requisição**.

O corpo da **requisição** é a informação enviada pelo cliente para sua API. O corpo da **resposta** é a informação que sua API envia para o cliente.

Cuando necesitas enviar datos desde un cliente (digamos, un navegador) a tu API, los envías como un **request body**.

Un **request** body es un dato enviado por el cliente a tu API. Un **response** body es el dato que tu API envía al cliente.
